Usage

Here's how to implement custom validation for unique country phone numbers and emails with a specified domain:

public class MyValidator : AbstractValidator<MyModel>
{
    public MyValidator()
    {
        RuleFor(x => x.PhoneNumber).NigerianPhoneNumber();
        RuleFor(x => x.Email).ValidEmailAddress("example.com");
        // Additional rules...
    }
}

Examples

Validate a Nigerian Phone Number

public class UserValidator : AbstractValidator<User>
{
    public UserValidator()
    {
        RuleFor(user => user.PhoneNumber).NigerianPhoneNumber();
    }
}

Validate an Email Address with a Specific Domain

public class CustomerValidator : AbstractValidator<Customer>
{
    public CustomerValidator()
